Dichlorodiphenyltrichloroethane (DDT) Dichlorodiphenyltrichloroethane (DDT) is an insecticide used in agriculture. The United States banned the use of DDT in 1972, but some countries still use the chemical.

For example, the grass that the cows eat is sprayed with DDT and the cow eats it. Then the cow's milk is infected with DDT. The people drink the milk and get DDT in their system and as the DDT moves up the food chain, it gets increasingly concentrated and more dangerous.
